I think the models now allow that the supernova may not blast planets
out of the system. [One of our physics experts should be able to
compute the force exerted on a planet by the SN (at least from an
"energy impact" standpoint) and determine whether it can really
deflect it from orbit].
Since, there are models where neutron stars and/or white
dwarfs may suck matter from a nearby star, it is possible
that this could lead to a disk that might form planets.
[This seems iffy though.]
The planets could certainly be "collected" during near stellar collisions.

(a) They like devoting all of their energy resources to rebuilding their
nanomachines damaged by high radiation levels. Perhaps because life as an
SI around a normal star gets boring and putting yourself in a high-rad
environment has to make things a lot more difficult (i.e. exciting).
(b) The planet is an "off-the-neutron-star" communication station. Neutron
stars would in theory provide the densest "computronium". I have no
idea how you would get signals "in" or "out" however. [What happens
to photons hitting a ball of neutrons????]. Perhaps changes in the
vibration or spin state of the neutron star are "read" by the planet
and relayed to other ultra-super-intelligences (neutron-star computers).
(c) The planet has been placed there by the benevolent ETAI association
to allow worm-brains like us who only have radio telescopes and
haven't figured out high resolution visible spectroscopy to detect planets
and go all warm & fuzzy thinking about the possibility of an inhabited
universe.
